[0002] Parallel seam welding is a resistance welding technique widely used in the hermetic packaging of microelectronic devices. Parallel seam welding primarily involves two electrodes (usually conical or cylindrical) contacting a metal cover plate to form a closed loop. When current flows through this loop, extremely high localized heat is generated at the contact point between the electrodes and the cover plate, melting the metal layer on the cover plate and forming a continuous and complete weld area.

The existing technology uses manual cover plate operation, which is inefficient and difficult to control the positional accuracy, and cannot meet the requirements of batch operation. Therefore, a parallel seam welding cover plate positioning device is proposed to address the above problems. Utility Model Content

Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of the present utility model.

[0024] Specific implementation examples are given below.

[0025] Example 1

[0026] Please see Figure 1-5 As shown, a parallel seam welded cover plate positioning device includes a worktable 11; a welding assembly and a product clamp 12 for positioning the product are installed on the worktable 11; the welding assembly includes a first drive device 13, a support 14, a welding machine and a second suction nozzle 16, the support 14 is installed on the first drive device 13, the first drive device 13 can drive the support 14 to move in the X-axis and Z-axis directions, a vertical frame 15 is installed on the side of the support 14, the second suction nozzle 16 is installed on the support 14, the welding machine is installed on the worktable 11, and the welding roller 17 of the welding machine is installed at the bottom of the vertical frame 15;

[0027] In use, the product is fixed on the product fixture 12 and positioned. The first drive device 13 can drive the support 14 to move along the X and Z axes. The second suction nozzle 16, the vertical frame 15, and the welding roller 17 are installed on the support 14. The second suction nozzle 16 picks up the cover plate and places it on top of the product. After the cover plate is attached to the base of the product, the welding roller 17 presses down on the edge of the cover plate. The welding machine starts pre-welding discharge, and the welding roller 17 pre-welds and fixes the cover plate. With the above settings, the workload of manual operation can be reduced and the welding efficiency can be improved to meet the needs of large-scale operation.

[0028] Furthermore, such as Figure 2As shown, the system also includes a cover plate loading assembly and a cover plate clamp 21 for positioning the cover plate. The cover plate clamp 21 is mounted on the worktable 11. The cover plate loading assembly includes a second drive device 22 and a first suction nozzle 24. The second drive device 22 is mounted on the top of the worktable 11, and a fixed base 23 is mounted on the second drive device 22. The first suction nozzle 24 is mounted on the fixed base 23. The second drive device 22 can drive the fixed base 23 to move along the Y-axis, and the first suction nozzle 24 can pick up the cover plate from the cover plate clamp 21. A cover plate positioning platform 25 for positioning the cover plate is mounted on the top of the worktable 11. In use, the cover plate clamp 21 is used to store material and position the cover plate. Then, the first suction nozzle 24 on the fixed base 23 is moved by the second drive device 22 to pick up the cover plate and place it on the cover plate positioning platform 25. After the positioning platform positions the cover plate, it waits for the second suction nozzle 16 to pick it up, thereby realizing automatic loading of the cover plate.

[0029] Furthermore, such as Figure 1-4 As shown, it also includes a servo motor 31 and a third drive device 32. The servo motor 31 is mounted on the worktable 11, and the third drive device 32 is mounted on the output end of the servo motor 31. The product fixture 12 is mounted on the third drive device 32. The third drive device 32 can drive the product fixture 12 to move along the X-axis and Y-axis, and the servo motor 31 can drive the product fixture 12 to rotate. A base-top camera 41 is mounted on the top of the worktable 11 via a bracket, and a cover-bottom camera 42 is mounted on the bottom of the cover plate positioning platform 25. In use, the second suction... The nozzle 16 picks up the cover plate from the positioning platform and moves it to the position (X, Y and angle) captured by the camera 42 at the bottom of the cover plate. Then, the third drive device 32 and the servo motor 31 move the product fixture 12 synchronously to the position below the camera 41 at the top of the base to capture the position of the product base on the fixture. After the vision software calculates the position and angle of the product fixture 12 in the Y-axis direction, the second suction nozzle 16 moves the cover plate in the X-axis direction and then presses the cover plate down in the Z-axis direction to accurately fit the base of the product. This achieves automatic cover plate positioning and automatic vision positioning, which is highly efficient, accurate and stable.

[0030] Furthermore, such as Figure 5 As shown, the vertical frame 15 and the support 14 are slidably connected by a slide rail 5. A pressure adjustment component is installed on the top of the vertical frame 15, which can adjust the welding pressure of the welding roller 17. The pressure adjustment component includes a vertical rod 61 and counterweights 62. The vertical rod 61 is fixed to the top of the vertical frame 15, and multiple counterweights 62 are sleeved on the vertical rod 61. In use, the welding pressure of the welding roller 17 is provided by the counterweights 62. The welding pressure can be adjusted by increasing or decreasing the counterweights 62 for products of different sizes, thereby improving the applicable range.

[0031] The bottom of the workbench 11 is equipped with support legs.

[0032] Example 2

[0033] like Figure 6 As shown, the pressure regulating assembly includes a top seat 71, a base 75, a screw 72, and a spring 73. The base 75 is fixed to the vertical frame 15, and the top seat 71 is fixed to the top of the support 14. The screw 72 passes through the top seat 71 and is threadedly connected to it. A support rod 74 is fixed to the bottom end of the screw 72, and the bottom end of the support rod 74 passes through the base 75 and is slidably connected to it. The spring 73 is sleeved on the support rod 74. In this embodiment, the welding pressure exerted by the welding roller 17 is provided by the spring 73. By rotating the screw 72, the screw 72 can compress the spring 73, thereby adjusting the tension of the spring 73 and thus adjusting the welding pressure, thereby improving the applicable range.

[0034] Working principle: During use, the product is fixed on the product fixture 12 and positioned. The first drive device 13 drives the support 14 to move along the X and Z axes. The second suction nozzle 16, the vertical frame 15, and the welding roller 17 are installed on the support 14. The second suction nozzle 16 picks up the cover plate and places it on top of the product. After the cover plate is in contact with the base of the product, the welding roller 17 presses down on the edge of the cover plate. The welding machine starts pre-welding discharge, and the welding roller 17 pre-welds and fixes the cover plate. With the above settings, the workload of manual operation can be reduced and the welding efficiency can be improved to meet the needs of large-scale operation. The cover plate fixture 21 is used to store materials and position the cover plate. Then, the second drive device 22 drives the first suction nozzle 24 on the fixed base 23 to move. The first suction nozzle 24 picks up the cover plate and places it on the cover plate positioning platform 25. After the cover plate is positioned, it waits for the second suction nozzle 16 to pick it up, thus realizing automatic feeding of the cover plate. In use, the second suction nozzle 16 picks up the cover plate from the positioning platform and moves it to the position (X, Y and angle) captured by the camera 42 at the bottom of the cover plate. Then, the third drive device 32 and the servo motor 31 move the product fixture 12 synchronously, moving it to the position of the product base on the top of the base under the camera 41 to capture the position of the product base on the fixture. After the vision software calculates the algorithm, the product fixture 12 moves to the correct position and angle in the Y-axis direction. Then, the second suction nozzle 16 moves the cover plate in the X-axis direction, and then presses the cover plate down in the Z-axis direction to accurately fit the base of the product. This realizes automatic cover plate positioning and automatic vision positioning, which is highly efficient, accurate and stable. The welding pressure of the welding roller 17 is provided by the counterweight 62. The welding pressure can be adjusted by increasing or decreasing the counterweight 62 for products of different sizes, thereby improving the applicable range.
